Time Different on iPad than EXIF Header

[tiedyemargie]

I am working on a Mac OS 10.12.6 and have (I think) successfully modified the header of my photo/.JPG file to show the date/time I want:

exiftool -AllDates -P *.JPG
Date/Time Original           : 2015:02:22 08:11:53
Create Date                     : 2015:02:22 08:11:53
Modify Date                     : 2015:02:22 08:11:53

When I load the image in the directory above to my iPad the time shows 7:11 instead of 8:11.

I've spent hours trying to figure out how to get the photo to show 8:11 on my iPad and have had no success.

Any input or advice would be greatly appreciated.

Thank you

Try this:
exiftool -G1 -a -s -time:all *.jpg
to see all the time based tags.  Maybe one of them is the cause.

Another possibility might be a time zone difference.

I live on the East Coast, USA (Georgia) and the photos were taken also on the East Coast (Florida) so the time zone should be the same.

The photos were taken not during DST and it is DST now, but I think if that were the problem the time on the iPad would say 9:11 instead 7:11.

I've done extensive fiddling with the time on the iPad and nothing I've tried has changed the time on the photo to anything other than 7:11.

The photos I am trying to sort by time are from 3 sources (2 cameras and my iPhone).  Only the iPhone photos have the 1 hour difference on the iPad and it is causing the photos to be out of order.  At some point I'm going to have to just let it go, but after spending so much time on this I'd really like to get it working

Any other ideas or suggestions would be greatly appreciated.

Unfortunately, I'm out of suggestions.  The time stamps in the file are not the problem, and, as you said, it's not a timezone problem.  Unfortunately, I don't have access to an iPad to do further testing.

I understand.

Thank you!!

Perhaps it's a daylight savings problem (bug). Move the date to e.g. somewhere in June 2017  and see if the time show is suddenly correct.

You are correct.  I changed the date/time of the photo to June and now the time shows 8:11 instead of 7:11

Wow.  Thank you!

i am pleased to report that I now have photos from 2 of the 3 different sources on my iPad and they are in order.   

I still have photos form the 3rd camera and the videos to sort out, but am definitely on the right track. 

I really did try to figure it out on my own, but needed help this time.

Thank you all so, so much!
